AMA is a documentary-note style. In-text citations are numbered and the reference list is in numerical order.
In text citations are in superscript1 in order of citation (the first citation is 1, the next is 2, and so on). If you use the same source again, you keep the same number. The source used for the first citation is always 1, even if it is used again after 5.
Only use surnames of the authors when mentioning them in the text. For 2 authors, use both surnames; for more than 2 authors, use the first author's surname follwed by "et al".

Superscript numbers
The numbers in text are in superscript1 and occur at the end of the clause in which you used the information.
They occur outside “quotation marks,”2 commas,3 (parentheses)4 and full stops.5 But, they occur inside semicolons6; and colons7:
Do not leave a space between the last letter or punctuation mark and the number.
Citing more than one work at a time
Use commas to show that more than one work is being cited, and use hyphens for several works that would be numbered sequentially:
These side effects can have implications for the patient's heart health, as numerous studies have shown.1,3,6-9

Your reference list should begin on a new page following the text of your paper.
Formatting Tips:
Number references should be listed in the order they appear in the text. Do not alphabetize.
Do not indent if the citation extends to a second line.
Authors are listed with the last name first followed by the first and middle initials without periods. (E.g.: Windley, HA)
Up to 6 author names should be listed. Over 6 authors, list only the first 3, followed by "et al."
Journal titles abbreviated according to PubMed abbreviations and italicized.
In journal titles, capitalize all major words.
For online journals, the DOI is preferred over the URL link.
In book titles, capitalize all major words.
When URLs are used, ensure that they are a direct as possible and the link still functions as close to publication as possible.

AI programs should never be included in the reference list as an author or creator of content.
"Nonhuman artificial intelligence, language models, machine learning, or similar technologies cannot be listed as authors because these technologies do not qualify for authorship." (AMA Manual, section 5.1.12)
AMA recommends you add a few sentences about your use of AI and the model.
Acknowledgement Tips:
Write an acknowledgement in the acknowledgement section
Describe how AI was used in the Methods section
If it was used to generate ideas, maybe put it in the introduction
If it was used to edit the paper, maybe put it in the conclusion
AI should be used as an in-text citation only. However, there are no concrete guidelines. Below are some examples of how to incorporate AI acknowledgements in the text:
"On August 3, 2023, I used AI to summarize five research papers, to help me determine which idea was least studied and focus my topics for this essay. I used ChatGPT, model 3.5, made by OpenAI, hosted at https://chat.openai.com/."
"The AI responses concerning topics of low and moderate seriousness were written on January 12, 2023, using the August 3, 2023, version of a large language model (ChatGPT, model GPT-4; OpenAI)."
